Optimal quantum circuits for general phase estimation

Optimal quantum circuits for general phase estimation

Show other versions (1)

We address the problem of estimating the phase phi given N copies of the phase rotation gate u(phi). We consider, for the first time, the optimization of the general case where the circuit consists of an arbitrary input state, followed by any arrangement of the N phase rotations interspersed with ar...
